Merge tag 'omap-devel-late-for-v3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into late/soc
These changes take us a step closer to merging the common clock framework for omap but unfortunately these patches were not ready for merging earlier. See also the notes below on the dependencies these patches have, they are based on a merge of sereral branches already merged. From Paul Walmsley <paul@pwsan.com>: OMAP patches intended for the 3.7 merge window: - Runtime PM conversions for the GPMC and RNG IP blocks - Preparation patches for the OMAP common clock framework conversion - clkdev alias additions required by other drivers - Performance Monitoring Unit (PMU) support for OMAP2, 3, and non-4430 OMAP4 - OMAP hwmod code and data improvements - Preparation patches for the IOMMU runtime PM conversion - Preparation patches for OMAP4 full-chip retention support Based on a merge of v3.6-rc6, the omap-cleanup-b-for-3.7 tag (7852ec0536ca39cefffc6301dc77f8ae55592926),the cleanup-fixes-for-v3.7 tag (de6ca33a96a6bf61fcb91d3d399703e19ead9d1e), and the omap-devel-am33xx-for-v3.7 tag (11964f53eb4d9ce59a058be9999d9cfcb1ced878), due to dependencies. * tag 'omap-devel-late-for-v3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: (281 commits) ARM: OMAP4460/4470: PMU: Enable PMU for OMAP4460/70 ARM: OMAP2+: PMU: Add runtime PM support ARM: OMAP4430: PMU: prepare to create PMU device via HWMOD ARM: OMAP2+: PMU: Convert OMAP2/3 devices to use HWMOD ARM: OMAP3: hwmod data: Add debugss HWMOD data ARM: OMAP2+: clockdomain/hwmod: add workaround for EMU clockdomain idle problems ARM: OMAP: Add a timer attribute for timers that can interrupt the DSP hwrng: OMAP: remove SoC restrictions from driver registration ARM: OMAP: split OMAP1, OMAP2+ RNG device registration hwrng: OMAP: convert to use runtime PM hwrng: OMAP: store per-device data in per-device variables, not file statics ARM: OMAP2xxx: hwmod/CM: add RNG integration data ARM: OMAP2+: gpmc: minimal driver support ARM: OMAP2+: gpmc: Adapt to HWMOD ARM: OMAP2/3: hwmod data: add gpmc ARM: OMAP4: hwmod data: add mmu hwmod for ipu and dsp ARM: OMAP3: hwmod data: add mmu data for iva and isp ARM: OMAP: iommu: fix including iommu.h without IOMMU_API selected ARM: OMAP4: hwmod data: add missing HWMOD_NO_IDLEST flags to some PRCM IP blocks ARM: OMAP4: hwmod data: make *phy_48m* as the main_clk of ocp2scp ...
